Compliments of Mary Brown: I know some people are probably having a significant issue with the air quality.  Others may just be trying to decide where to plan their next adventure.  Either way it could be a helpful website.  I sent the link to my daughter in Missoula because their girls are actually having a hard time breathing right now, and they're trying to decide where to escape for the weekend. https://www.airnow.gov/index.cfm?action=airnow.local_state
